Preventing a Frozen Water Service

Pipes exposed to severe cold, like outdoor hose bibs, and water supply pipes in unheated interior areas

like basements, crawl spaces, utility rooms can be prone to freezing.

The Utility offers customers the following winter tips to prevent costly and inconvenient repairs brought about by frozen or ruptured pipes:

            • Keep basement temperatures above freezing by opening furnace duct vents.
            • Eliminate cold drafts -repair broken windows and doors and keep them tightly closed
            • Insulate exterior walls
            • Seal all air leaks in crawl spaces and basements
            • Turn off water to outside faucets, remove hoses and drain the pipes
            • Open the door to utility rooms and cabinets where pipes are located to allow warm air to circulate
            • Make frequent use of your water. If you will be gone for a few days, run water from a faucet at a small stream to allow water to continuously flow through pipes.
            • If you own a property that is currently vacant, turn the water off at the inlet valve located near the water meter and drain pipes down.
